Package includes BOTH an Ultra Sleek Vortex 140mm Fan and a Static Booster in white. The Static Booster helps to focus the direction of the air， increasing static pressure. The higher static pressure helps to improve cooling performance， particularly on radiators.
With the Static Booster installed on the Ultra Sleek Vortex， the width of the fan is increased from 15mm to 25mm. The Booster can easily be removed to restore the Ultra Sleek Vortex to 15mm in thickness，
Extremely quiet! Only 9 dBa at its lowest speed and 18 dBa at full speed! Equipped with 4-Pin PWM for adjustable fan speeds from 300 to 1000 RPM， allowing for almost absolute silence or high performance.
Specially engineered 17 blade fan design offers excellent airflow， pushing through 98 CFM of air. Dual Ball Bearing offers long life.
IMPORTANT NOTE: This 140mm case fan is designed to be mounted on 120mm mounts. It will not fit 140mm mounts. For cases with two 120mm mounts directly next to each other， consider using the Ultra Sleek Vortex 12.
